Please see this outstanding lecture by Cyril of Jerusalem, written in the mid to late 300's on the words from our Creed, "Maker of Heaven and Earth, and of all things visible and invisible." Not only is it spirituallyl uplifting, but it serves to counter the vapid notions of evolution with which we are inundated; and which serve to destroy faith in Christ, Christian hope, and human worth. Without the knowledge of, and faith, in our God, Creator, Sustainer and Redeemer, we sink into hopeless depression, sorrow, futility and anxiety. But when we know and believe that our Creator, God and Heavenly Father made us, and still preserves us, and will renew the face of the earth by His Spirit, then we are returned to equilibrium; to spiritual, mental and physical health.
